Read this one in the '90s.
The cider barrel on tap in a British pub seems to have run dry, despite not having been on tap very long and still weighing far more than an empty barrel should weigh. When it is opened, a body is found inside. The body turns out to be a Yank airman or soldier who had disappeared during WW II. (Not sure how many years after the war this is set; I think maybe in the '50s.) The Yank had had some connexion the daughter of the farmer who had made the cider in that barrel.
